APPARATUS FOR CASTING CURVED STEREOTYPE PLATES.

Application filed June '23, 1926. Serial No. 118,158.

The general object of this invention is to produce curved stereotype plates for use on printing machines, such as the multigraph.

Another object of the invention is to make the device adjustable so that plates of difierent sizes and of different thicknesses can be produced.

This invention also consists in certain other features of construction and. in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an end view of the device.

Figure 2 is a top plan view thereof.

Figure 3 is a vertical sectional view.

Figure 4 is a view showing the parts separated.

Figure 5 is a detail sectional view showing the metal cut and mat in position between the parts.

Figure 6 is an enlarged view of the mat.

Figure 7 is a view of the cut. 7

In these views, 1 indicates the supporting block which is provided with a semi-circular recess to receive and support the drag or lower member 2. The edges of this member extend above the block and these edges are provided with the centrally arranged outwardly curved portions 3 which form the pouring lips. The upper member or cope is shown at 4 and is in the form of a cylinder. This member is to rest within the lower member, said lower member receiving the mat 5 from which the 'cut' is to be formed. A pair of split rings 6 is movably held on the cylinder or cope by the coiled springs 7, each of which has its ends en gaging the hook-ed ends of each ring. These rings are adjusted on the cylinder. so that they will rest on the mat adjacent the ends thereof, as shown in Figure 3, so that said rings will support the cylinder above the mat and thus form a space for receiving the metal which forms the cut or stereotype plate 8. By pouring the metal in one of the lips 3, it will pass downwardly between the rings and fill the space between the mat and cylinder and thus form the cut. The parts hold the cuts on the machine.

are clamped together-by the clamp 9. By using the rings 6 of different sizes, the thickness of the cut can be made of the desired degree. By using the springs for connecting the ends of the rings together, the rings can be easily and quickly adjusted on the cylinder.

When the plate is to be used on a multigraph printing machine, it is trimmed andv small notches are filed in its longitudinal edges for receiving the metal clips used. to

the cuts or plates formed with this machine vwill be smooth, but should it bedesired to have ridges or lugs on the back of the plate for securing the plate to the printing segment, suchlugs can be cast with the cut by having depressions in the upper member to form such lugs.

With this invention, curved stereotype plates can be easily and quickly cast at low cost so that the user of a multigraph machine can produce his cuts at a low cost and with a small initial investment. 7

Itis thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims. I

What I claim is 1. A device of the class described comprising a base having a semi-circular recess therein for receiving a mat, a cylinder adapted to fit in the recess and a pair of rings embracing the cylinder and adapted to rest on the mat for forming a metal receiving space above the mat said rings being bodily movable on the cylinder so that they can be adjusted to any position thereon.

2. A device of the class described comprising a base having aserni-circular recess therein adapted to receive a mat, a cylinder fitting in the recess, a pair of split rings on the cylinder, a coiled spring connecting the ends of each ring together, said rings The backs of PATENT OFFICE.

resting upon the mat to form a metal repouring lip formed at the center of the base at one side thereof.

SIMON WERBNER.
